Black markets have always been there online, selling stolen credit card numbers, bank accounts and social media passwords; now the hackers want cheap Netflix, and this demand is also satisfied (illegally). According to a recent research of the ever-growing industry for stolen personal data, carried out by security company Symantec, the huge consumer interest in the popular streaming video service is being responded.

Nowadays, hackers often obtain account information via so-called “social engineering”, which lures people into providing their login details via a spam email or fake login page that looks like an official Netflix home page. They can also use other software that looks like the Netflix app but actually uses the site as a decoy, stealing login details once you sign in through it.

In most cases, hackers then sell this data cheaper that the official Netflix subscription rate of about $10 per month. The security firm can’t estimate the total number of compromised accounts, but it brought an example of one marketplace that claims to offer 300,000 accounts for as little as $0.25 each, with 7 day guarantee.

This Symantec research reminds the consumers they should closely protect digital passwords from various services that may not seem as valuable as a bank password or email login. It also points out that Netflix accounts can be used anywhere, and by 1 to 4 people at the same time. This means that if other 4 people start using your account, it could lock you out despite being a valid Netflix user.

Although Netflix representatives haven’t yet commented on the results of Symantec research, it is clear that managing fraud is a tough balancing act for the streaming service, despite the fact that sharing Netflix logins is a usual thing among roommates, partners and families.

Symantec was not the first company to research the problem: for example, McAfee released a similar report a few months ago, and also found similar fraudster schemes for HBO’s steaming service and Marvel’s digital comics site. The researchers agree that it is unclear how large the black market is for such services and to what extent it damages companies’ bottom lines. The official statistics from Netflix says that in December 2015 the service had over 75m subscribers, adding 5.59m users during the Q4 in 2015.
